Wrench Tip: Torquing Unreachable Fasteners

by Nikita Rushmanov

Have you ever looked at your service manual for a torque spec, only to curse, “What the hell were those engineers thinking?” We certainly have, but there is always a way to get things done by the book. The perfect example of an impossible torque spec is the driveshaft to differential flange on a 240sx. In this case, it’s impossible to get a socket on the nut because there is not enough room between the flange and the differential housing. Additionally, the hex head of the bolt on the other side is jammed against the flange, so you can’t torque that either. As a result of this, a lot of 240 owners we know never actually use a torque wrench on their driveshafts, instead opting to torque to “2 uga ugas” with an open ended wrench. To compliment this, we’ve also seen a few 240 driveshafts rattle loose, or in some cases come off completely, punching holes in the floor pan.

So what’s the solution? Let us show you!

The Cars of Knox Mountain Hill Climb

by Frank Ewald

There was something for everyone at Leavitt Machinery's Knox Mountain Hill Climb that recently took place in Kelowna, B.C. The spectacular views of Okanagan Lake surrounded by mountains truly set the scene for this event. The cars ranged from open wheel through fully caged track cars to street prepared and then vintage. These cars ranged from obviously well-used track toys to vehicles that looked like they would be more at home at a show and shine placement. Make no mistake, the drivers were all here for one thing: to find their personal best and, just maybe, become the King of the Hill!

Project EP3 Civic Si: Fixing EP3 Bumpsteer with Hardrace

by Mike Kojima

In prior editions of Project EP3 Civic Si, we went over the history of the car- the worst handling Civic made with suspension geometry taken right from the Stream minivan. Well, so far we have gotten rid of squishy rubber and added sway bars with help from Whiteline. We also got rid of the flaccid shocks with a set of coilovers from Fortune Auto. Now we will address bumpsteer issues with Hardrace!

Event Coverage: 2017 Indianapolis 500 Presented by PennGrade Oil, Part 1

by David Zipf

There is no place like Indy.  It’s big, it’s fast, it’s narrow, and the track is like no other on earth.  Even in this modern, high tech world, winning Indy is one of the toughest tasks in motor racing today.  The cars may be much faster and more reliable, but winning Indy in 2017 is still just as tough as it was in 1911.

Project EP3 Civic Si: Installing Fortune Auto 510 Coilovers!

by Mike Kojima

Over the past few installments of our EP3 project, we have been working on fixing on what is perhaps the car's major weak point, the handling. Previous Civics were known for excellent handling with 4-wheel multi-link suspension. The EP3 however, uses the suspension from a Japanese market Stream van in a really dumb case of parts bin engineering.

Tested! BMW 335i NGK Coils and Bosch Plugs

by Pablo Mazlumian

One of the problematic areas of the BMW 335's N54 3.0-liter twin-turbocharged engine is the ignition failing, specifically with the coils. And, unfortunately, a new set of coils and plugs can run you over $800 at the stealer. Today we show you how to refreshen those components with new OE replacements from Sparkplugs.com, and we save nearly $500!

Project EP3 Civic Si, Suspension Upgrades with Whiteline! 

by Mike Kojima

So everyone into Hondas just about universally ignores or even hates the dumpy EP3 Civic. The EP3 represents, to most Honda fans the generation of Civic where Honda lost their brand identity and started to make cookie cutter shitboxes.

Lessons in Turbo Technology with Garrett - Burst Containment

by Mike Kojima

What is burst containment for a turbocharger, and why is it important?  A turbocharger is a system that has a lot of potential to cause a lot of bad stuff to happen to drivers, spectators, and surrounding equipment.  Why, might you ask? Well, a typical turbocharger can spin at up to an unfathomable 200,000 rpm for a small frame turbo and a still amazing 90,000 rpm for a large frame turbo!  That is a ton of potentially ass-kicking force. We will show you how much later and it's enough to make you cringe.

Project STurdteen: Installing Progress Sway Bars

by Rathyna Gomer

To run sway bars or to not run sway bars? That is the question. In the drift world, there's been a reoccurring debate if there is any true benefit to running sway bars. Sometimes it comes down to the driver's preference and sort of drift "style" they're aiming to achieve. As the debate continues, we opted to run sway bars. Sensei Kojima tells me there's no other way!

Project EP3 Si: Going 5 Lug with Wheels from Enkei and Nitto NT05 Tires

by Mike Kojima

Now that we converted our EP3 Civic from 4 to 5 lug hubs and added big brakes, there was no going back.  In order to drive the car, we obviously needed to do something about our wheel situation.  Our goal was to stuff the biggest tires we could into the stock wheel wells.  Unlike our hellaflush brethren, we want big and we want traction, not stretching a narrow tire on a wide rim and stupid amounts of negative camber.

Project Infiniti G37S: Advan RZII Wheels & Nitto Invo Tires

by Aaron LaBeau

More than many other modifications on a project car, we suffer over wheel and tire choices the most. Mistakes are costly and easy due to sizing choices, but also aesthetically, it's really hard to get an idea of what a wheel will look like on your ride before it's installed. Or, you go down the road someone else has, making a guess on how much you want to trust someone else's judgement.

Japanese Cars That Don't Suck

by Mike Kojima

I pissed a lot of people off with my Japanese Cars Suck article a few weeks ago, where I expressed dismay at the boring state of the Japanese car industry. Japan Inc. seems to be producing either the uninspired transportation device or the trying too hard, over the top stuff that seems like something out of the Fast and the Furious or Transformers franchises.

Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

by Mike Kojima

In the last edition of Project EP3 Civic Si, we explained how we went about converting our car from 4 lug to 5 lug hubs. We did this for two reasons: one to take advantage of the larger selection of 4x114.3 bolt circle wheels available on the market and to take advantage of the larger RSX Type-S wheel bearings and axles to stiffen up the bearing system in anticipation of performance fixed caliper brakes and more power from a possible engine swap.

Turbo Tech: Calculating Turbocharger Compressor and Turbine Performance Advantage with the New Honeywell Garrett GTX Gen2

by Khiem Dinh

In our Turbo Tech series, we have covered a lot of segments of turbocharger performance. We have looked at various aspects of compressor efficiency and performance, turbocharger mapping, and turbo sizing and matching among other things. This time around, we are going to do some more calculations on the turbine side, calculating pressure ratio and wastegate flow along with estimating power gains from the Honeywell Garrett GTX Gen2 turbos over the first generation GTX. You better get your Excel spreadsheets warmed up.

The Blackbird Fabworx Morpheus Miata!

by Mike Kojima

The cars created by Moti Almagor of Blackbird Fabworx have always caught our attention. More for less has always been the theme his creations. The Blackbird Fabworx cars have always eked amazing speed out of stock, very low powered engines. Lightweight, meticulous care in chassis setup, balanced brakes and carefully thought out aerodynamics have had a harmonious interplay in developing incredible speed from very little horsepower.

Testing Meguiar's Two Step Headlight Restoration Kit!

by Mike Kojima

Any car that has the newer plastic headlights will experience weathering and yellowing eventually. This is caused by UV light exposure degrading the protective coating on the surface of the lights. Once the coating is eroded, UV light makes quick work of the clear plastic underneath, and the light becomes cloudy and yellow.
